To all whomit may concern:

. .Be-itknownthat I, SAMUEL SAUNDERS, subject of the King of Great Britain and Ireland, residing at-LS Lower .Morley street, Manchester, in the county of Lancaster, England, heating and ventilating engineer, have inventednew and useful Improvements in Automatic Controlling Means for .Heating and Lighting Installations and Such like, of which the following isia specification. v

Thispresent invention relates tozimprovements in automatic controlling means'for hpating and lighting installations and such 1i (e.

"It is known to employ alarm clocks capable of. being set, whereby when the alarm.

spindle 'moves, mechanism is released or actuated which (through weights or otherwise) operates dampers, or switches, or valves, etc., for the automatic performance ofsome particularoflice, and it is' to this class of device that my invention relates.

I make use of a carrying board or any appropriate fixture and on this I mount means for supporting or incasing an alarm clock. The clock may be removablefrom supports, or it may be carried'on a hinged or movable part ofthe casin'g'which is designed to expose the face of the clock at the front. Such a clock can be readily fixed in theliinged part ofthe casing. and so is easily swung out on the casing hinges for winding-up, setting and other purposes. I use an eight day or otherrlong period clock. withan alarm mechanism capable of being set at any time in the twenty-four hour period asis known, andI may arrange to silence the alarm sounding appliances if such are fitted on the clock. Uncertain alarm clocks,a press-down or other device iszfitted,which, when acted on, stops the alarm.

I propose to use such an arrangement of mechanism as will only call fora Winding of the clock and the alarm spindle say once a Week, and so attention to the release oractuating mechanism once a day is alone necessary and-theral'arm.needs'no daily winding. I alsouse Sucha'combination as will prevent the alarm. wind. spindle from running down completely should the release oractuating mechanism be not re-set on any particular day.

Tocmry utfmy object-I preferably ar-.

range to act on the mechanism which stops the alarm wind spindle, immediately the same has performed its function and effected release. -T he way of doing this would vary according to the form of stop alarm appliance. In that class of clock where a push down spindle exists, a pivoted lever would form a simple actuating means.

The use of time recording mechanism for performing a service automatically at inter vals over a period of days has been hampered by inability to skip or miss a day or a number of days and yet to be able to bring the mechanism into action after skipping or missing a period. As an example, when dealing with automaticheating or light or other controlling means, it is obvious that in the majority of cases it is desirable to be able to suspend action on Sundays without in terfering with due performance of the desired o'liice on the Monday. I so arrange that a day or days may be cut out or omitted by the mechanism.

In the simplest way of effecting this part of my object I arrange to make the release leverinoperative, when desired, but by means which make such release lever again automatically operative after being out of action for a period of 2-1 hours or other desired length of time.

fMy invention is illustrated in the attached drawings, wherein Figure 1 shows a front View of clock controlled mechanism embodying the features of my invention.

Fig. 2 is a sectional View.

Fig. 3 is a face view and shows the clock turned away from the support through an arc of 180, to more fully expose the mechanism.

Figs. 4 and 5 are detail views of the lever mechanism which acts onthe alarm pushdown spindle to at once stop the alarm wind mechanism as Soon as the desired oflice has been performed.

' Fig. (3 is a detail View of the release lever pivot or fulcrum.

Figs. 7 and 8 are enlarged detail views of the combined means which permit of the cutting-out of a day or days.

' Indescribing my invention in detail I Will deal with mechanism suitable for an alarm clock'with theknown push-down pindle. Such an alarm clock is shown inthe drawings and is marked a. It is removably mounted on the movable part of acasing a,

30 lever arm. The result of this construction is, that when the alarm wind spindle 6 ra the part a being fixed to the supporting board A, and the part a carryingthe clock being hinged at a I. fitythe alarm wind spindle?) with a small plate I) or the like having two projecting piiislffl) which device also serves for winding the said spindle b. I usea release lever c, 0, conveniently centered on a castmetal plate 0 and the upper part 0 of this lever lies contained in the Wooden casing which inclosesthe clock,the lever-lying behind or in rear of the clock when the casing is closed and being guided by the slotted bracket j. The lever is acted upon by a small plunger cZbacked-up by a spring; or

"it might be held up by a weight or the like.

' Such lever has a projection 0* which is acted upon by the pins b 6 on the small plate b on the alarm wind spindle Z) when-the alarm goes OE, and also another projection '0 whlch operates the lever e to-act on the push down spindle.

. This lever e is suitably shaped and carried on a projecting post or spindle and has an arm 6 to act on the push down spmdle f of the alarm clock and a longer arm-e which normally ,rests on a stop-c Upon such longer'arm' is a triangular plate 9 pivoted at g, the vertical edge of said plate normally resting against a pin 9? on the long tates, one of its pins 6 6 acts on the part 0* of the release lever 0 and moves it angularly and say to'the right as will be understood. In moving to the right, the projection 0 on the upper end of the release :lever pushes past and displaces the pivoted triangular plate 9 without influencing the pivoted lever c. When the pin 79 has moved the release lever 0 so as to free the release or disengaging or actuating mechanism, the pin escapes clear of said lever, whereuponuthe spring pressed plunger (Z at once pushes back the release lever a ready fOIf f8 Setlll11g,

In pushing back the release lever 0,. the upper projection 0 encounters the pivoted triangular piece 9 and so the pivoted. lever e is at once actuated to operate the push, down spindle f and so to stop the alarm wind spindle. I find that about half'a revolution of the alarm wind spindle is enough move- 'ment for the object in view, so that the pin plate automatically comes into proper positionev ery time, but this may vary consid' erably, f1 :1 may use a rotatory grooved pulley h (or other'geardevic'e) with hand-lever h, in

. combination with the release lever, said'puh leydevice being centered on astud Zfi'onthe cast plate 0 The grooved pulleyhasapin k whichjen a es a notch'or-cut-awa or-I r I a: b V i I p t1on c" in the release lever half 0 ,whereby:

the weights 2' supported on thelchainii, and which weights do .the workpare held suspended. The grooved pulley h has attached.

to it flexible connections such as a chain r or chains or other motion communicating devices to operate the dampers, doors,

switches, valves, or such like, which require leased, the weights i turn same and effect. a pulling on the chain lc or the like. 1 If the releasexlever 0 0 piece or asingle entity actuation of the control mechanism would take place at every 7 were made in one control, whereby when the pulley h is'removement of the alarm-windspindle,but, j for the'reasons indicated (thatiis the power to cutout a day or days at will)'Iprefer to make the release lever in two parts a 7 0 the upper part 0 being hinged or jointed to or Working on the samepivot o as the lower, the complete lever having a fulcrum .say coinciding with the hing or joint at the point 0 The upper half of the release leveris,

as already stated, acted on by the plunger 61 backed up-by a spring or otherwise returned to its requiredpositionr From the lower half of therelease lever, extends an armor support .0, which is bored and carries a quadrant or notched disk m shown as cut with eight teeth to providefor service over a period of 7 days. disk is movable around a center pin m and has a stop-piece m which, when in the position seen in Fig. 7 abuts against the arm 0 To the part c of the release lever, is attached va pawl or catch a fulcrumed at n" the teeth. The effect of this is, that when. the

alarm next goes off, the quadrant or notched disk aloneis moved or advanced a tooth and the same on thesecond and third days, but

The quadrant or notched lOO on the third day .theposition is such that-the so on the fourth day thelrelease leverflas a whole'is actuated; and the desiredoffice performed automatically at the predetermined time; .1 1".

Obviously the cutting out form of connection-used with the release lever-maybe varied, but I have illustrated the simplest arrangement known to me.

pin or stop me has reachedthearms a and f 1- By myinvention I can'doallrthat neces- 'sary witha weekly windingof-theclock and the alarm spindle, and-TI actuate thestop}, alarm spindle mechanism immediatelyfthei automatic ofhce is performedx Itis also obvious I arrange for the actuation of the stop, alarm mechanism in the samemanner; (even fthe release lever or the like, due to care-t out a day or days being the important features.

I wish it to be understood that mechanism embodying the features described, would require to be of somewhat varied form according to the purpose in View.

The invention is particularly useful for the automatic openings of draft doors, dampers, and the like of heating plant at a predetermined time in the early morning before the arrival of the workers whereby a working temperature is assured without requiring manual attention before opening time.
